VP Overlay Chart for Profile Projector/Optical Comparators (Customizable)

CUSTOM CERTIFICATION SERVICES and DOCUMENTS

VP can also help you in the certification and inspection of most any precision measuring instrument. We have certified customer supplied charts, scales, reticles, stage micrometers. graticles, loupes, calibration targets, etc.

Level  1 – GENERAL CERTIFICATE OF CONFORMANCE

This is our basic certificate and is issued with every item shipped. No serial numbers or actual measurements are stated on the certificate.

Level 2- CERTIFICATE OF ACCURACY – Short Form

This certificate is provided for a product that has been inspected visually to ensure that it’s accuracy is within the value stated on the certificate. A serial number is assigned and is placed on the document and the product.

Level 3 – CERTIFICATE OF ACCURACY – Long Form

This certificate is provided for a product that has been inspected with a measurement device. A deviation report is generated detailing point by inspection of relevant features per the engineering drawing. A serial number is assigned and is placed on the document and the product.

Level 4 – CERTIFICATE OF ACCURACY – 3rd Party Inspection

This certificate is provided for a product that has been inspected with a measurement device. A deviation report is generated detailing point by inspection of relevant features per the engineering drawing. A serial number is assigned and is placed on the document and the product. A third party inspection report is provided. This report documents additional information specified in the IEC/ISO 17025:1999 (E) requirement booklet.

A custom comparator chart can solve a lot of problems quickly and inexpensively. Our design group has been creating “Special Application” charts for over 35 years. We can design and manufacture a comparator chart dedicated to your part and perfectly suited to your checking application.

We can create a chart from your part drawing or electronic CAD file. Features can include multiple views, graphic & numerical tolerances, datums, and theoreticals. The electronic files for charts are maintained for easy and inexpensive duplication and/or modification when a revision crops up.

A VP custom comparator chart can help you simplify a complex inspection job for your quality system.
